Labor United

Labor United (UP) is a minor social democratic party in Poland that was founded by Waldemar Witkowski in June 1992. At its height in 1993, the party held 41/460 Sejm seats. In 2001, the party joined the Democratic Left Alliance (SLD) in an electoral coalition, but some members would defect to Social Democracy of Poland, a splintergroup of the SLD. By 2017, Labor United was a marginalized party, holding just 1/51 European Parliament seats and 1/555 Regional assemblies.
